It’s easy come, easy go for former Miss Norway Monica Hansen. Last summer, the Playboy model won a $550,000 default judgment against Miami plastic surgeon Dr. Leonard “Boob God” Hochstein for posting photos of her buxom, blond self on his Web site to help drum up business — allegedly without her permission. But a California court has tossed that judgment and put the case back on track for a trial. The Post’s Dan Mangan recently reported Hochstein has a November 2008 e-mail that Hansen allegedly sent Hollywood madam Michelle Braun reading, “Yes honey I did let Lenny use the pictures . . . I am not going to sue.” Hochstein now says he’ll “be able to . . . tell my side of the story. The truth about [Hansen] will come out that she is a person whose morals are questionable at best and a liar.” Hansen’s lawyer, Tim Hall, shot back that Hansen didn’t write the e-mail to Braun and that Hochstein has “made all kinds of accusations . . . patently untrue.”
